mourns PAD.

Application filed May 1,1928. Serial No. 635,858.

The'invention relates to ironing pads as employed in ironing tables for pressing or in ironing machines, for example, of the character set forth in U. S. Letters Patent No. 1,054,407, granted me the 25th day 'of February, 1913. The pad disclosed in said. patent consists substantially of a base plate upon which are secured a plurality of adjacent and helically coiled springs, the latter being covered by suitable caps which support afabric top composed of a number of layers of suitable padding material.

The present invention has for its object to provide a substitute for the present type of fabric padding generally employed in connection with iromng pads and especially in connection with the type of spring pad set forth in the-aforesaid patent. In the type of resilient pad disclosed therein, it will be noted that the fabric covering is in direct contact with metal, viz: the caps for the individual spring members; and the present invention, in addition to dis ensing" with a large proportion of the fabric padding employed for the ironing surface, has for a further object to prevent contact of the I latter with any metal portion of the padas a whole. A still further object of the invention consists in' providing an intermedi ate and independently resilient medium'between the actual ironing surface and the re-' silient support. In the provision of the intermediate resilient medium and especially in view of the elimination of overheating thru prevention of direct metalliccontact with the covering the wear on the latter is materially reduced and charring and burning of same obviated.

The nature of the invention, however, will best be understood when described in connection with the accompanying drawings, in which- 1 v Fig.1 is a plan of one type of pad-embodying the invention and with a portion of the ironing surface cloth removed.

Fig. 2 is a fragmentary detail view illustrating the novel padding.

Figs. 3 and 4 are fragmentary views illus- -trating modifications. i

Similar characters of reference designate corresponding parts thruout the several views. v

Referring to the drawings, the pad may be of variousshapes, for example, of the flat type-such as employed on an ironing table;

' the square t is suitable for the various shapes employed in ironing apparatus. The pad is shown as composed of a base plate 10 upon which is mounted a plurality of adjacently disposed resilient members, as the coil springs-11 with Y convolutions reduced at an end or ends and as is more particularly set forth in my U. S. Patent No. 1,466,363. These resilient members may be secured in any suitable manner to the base plate, for example, as shown in the aforesaid U. S. Letters Patent; and at their tops may be covered with removable caps 12 similarly to the arrangement illustrated in the aforesaid Letters Patent. They may further be secured against displacement from their springs, 1n manner more particularly shown in my U. S. Letters Patent No. 1,445,399, by providing an indentation 13 in the wall thereof, which indentation will then cooperate with the convolutionsof the sprin In accordance wit the invention, the usual padding or covering is not supported by the tops of these caps 12 or by the'tops of the. springs 11 as has been the practice heretofore and as is shown in my said Letters V Patent; but there is carried by the individual springs, as in attaching to .each individual cap or forming integrally therewith, a suitable retainer member orreceptacle' 15. This member is of rigid material as metal and preferably in the nature of a cup which may be of various shapes, preferably hexagonal, as shown in Figs. land 2, although e illustrated in Fig. 3 provides for a satis actory substantially closed surface. Where a slight opening between the tops is not objectionable, the round type of receptacle illustrated in Fig. 4 may be employed. Into these individual adjoining receptacles are fitted snugly or may be posi tively heldthereby ieces or blocks of thermally insulating an heat resisting material 16, such as cork, asbestosor composition having proper resiliency for the purpose in view. These blocks are maintained against dislodgement bythe rigid metal cups 15 and are arranged to project'slightly above the edge thereof. Over the surface thus provided is usually. to be stretched a single layer or layers of finishing cloth 17, such as I of duck or like material, which provides the ironin surface. work, ilowever, such cloth covering may be entirely omitted.

.For certain vclasses of By this expedient, not only is the pad as a whole resilient thru the interposition of the springs 11, but each individual portion of the surface provided by blocks 16 afi'ords an individually resilient surface portion; andthe same need have but a single' layer or two as of duck or similar material as a finishing surface for the ironing op- -.eration. Each individual surface portion, moreover, is securely retained in its recepthe padding and thereby reduces the tend-- ency to overheat; When it doesbecome necessary. to renew the fabric ironing surface, it is then not. a case of providing an expensive pad 'composed of a considerable number of layers of material such as hair, cotton and wool of considerable thicknem, but merely of recovering with one or two layers of inexpensive material as duck, the more permanent cork or like material taking the place of same. 4

I claim 1. An ironing pad, comprising a support composed of a plurality of adjacent resilient members, rigid retainer members carried thereby, and resilient and heat insulating members held therein to afford an ironing surface. I

2. A11 ironing pad, comprising a support composed of a plurality of adjacent resllient members, receptacles individually carried by the said members, and individual heat insulating members fitting in and projecting above the edge of the receptacles to aflt'ord an ironing surface.
